this research, the pulling-out behavior of the RC footing of power transmission towers is simulated by 3-D FEM computation. In the program, nonlinear constitutive models are used for reinforced concrete and also for plain concrete, as a large volume of the footing is plain concrete. The results of computation show a similar capacity to those of the experimental data. Also, the shear cracks and yield of shear reinforcement in the computational results indicate the shear failure mode. As one full-scale experiment had been conducted for investigating the effect of size on the bearing capacity of RC footing, the FEM simulation was also carried out for this experiment. It was concluded that this code can predict the 3-D behavior of RC footing of different sizes.
